DENTAL GUSPIDOR s'rAnn,

Application filedNovember 2, 1920. Serial. No. 421,389.

To all whom it may concern: Be it known that I, HENRY E, WEBER, a citizenof the United States, residing at Canton, in the. county of Stark and State of Ohio,'have invented the new and useful Improvements in Dental Guspidor Stands, of whichthe following is a specification.

The invention relates to a pedestal or stand for supporting a dental cuspidor having water supply and waste connections, and the object of the improvement is to provide a tubular arm on the stand for supplying water and receiving an overflow at one side of the cuspidor bowl, with means permitting a rotation of the arm upon the axis of the stand for varying its lateral location. 2 p

The neat design and sanitary construction which are desirable and necessary for dental apparatus, render diificult the use of separate external pipes and fittings for carrying water to andfrom the side of a cuspidor. This difficulty is overcome by roviding a cylindric head rotatable upon the top of the stand, having'a'socket'for receiving and supporting the neck of the cuspidor and provided with an integral tubular arm having separate channels therein for carrying supply and waste water, the upper end of the arm being arranged for direct connection with special cuspidor fittings and the bottom of the head being arranged for direct connectionwith supply and waste pipes rising within the base of thestand. l

The accompanying drawings, forming part hereof, illustrate a preferred embodiment of the invention and a modification thereof, in which: I 1

Figure 1 is a side elevation of a dental cuspidor stand showing a preferred form of the improvement;

Fig. 2, an enlarged elevation section of the more pertinent parts of the same; and

Fig. 3, a similar section of a modification of the same.

Similar numerals refer to similar parts drawings.

The base 1 of the stand is in the form of a tubular pedestal which may be secured to the floor; in the hollow of which rise the water supply pipe 2 and the drain pipe 3, the lower ends ofwhich are preferably connected by slip unions 4 and 5 with corresponding fixed pipes 6 and 7 The hollow head 8 is cylindric in general form, and in the preferred form illustrated is provided "with an external annular shoulder 9 bearing on the rim 10 of the pedestal, within which the lower portion of the head depends in the form of the cup 11 from the bottom of which depends the nipple 12 forming the waste outlet from the hollow of the, head, to which nipple the upperv end of the waste pipe 3 is connected by the union 13, and preferably extends upward above the bottom of the cup as shown in Fi 2. I The rim 14 of the head forms a socket n which the neck 15 of the cuspidor bowl 16 is secured by a ring nut 17 and rubber ring 18. e V The tubular arm 19 extends from one side of the head first outward and then upward at one side of the bowl, which arm is preferably cast integral with the head, and within the arm are formed the separate channels 20 and 21 for carrying supply and waste water, the channel 20 being extended through the body of the head downward through the bottom of the head cup 11 from which depends the nipple 22 to which the upper end of the supply pipe is connected by he union 23, 'while the channel 21 extends downward to an opening near the bottom of the head cup 11 below the upper end ofthe drain pipe 3,- so as to permit fiow of water downward through the waste outlet nipple 12, and at the same time forming a trapfor water in the bottom of the cup.

Aseat 24 is preferably provided in the supply channel 20 for the stop valve 25; and the upper end of this channel is extended bythe separate tube26 upon which is connected the supply fitting 27 leading to a faucet 28 which may be controlled by a valve 29; andthe upper end of the channel 21 is extended by the separate tube 30 to which is connected the overflow fitting 31 extending through the rim portion of the bowl for receiving waste water therefrom.

The external annular groove 32 is provided in the hollow head below the bearing shoulder 9 thereof and set screws 33 are provided in the rim 10 of the pedestal, and it is evident that by loosening the set screws the hollow head may be rotated to bring the tubular arm 19 into various lateral positions upon the pedestal, and that by tightening the set screws the head will be fixed in a given position thereon.

For the purpose of permitting a rotation of the hollow head upon the pedestal, the upper end of the drain pipe is connected to the bottom of the head in the axis of the stand while its lower end is connected to the pern'ianent pipe 7 at one side of the axis of the stand, there being a reverse bend 34 in the pipe intermediate its end; and the upper end of the drain pipe 2 is connected to the hollow head at one side of the axis of the stand while its lower end is connected to the permanent pipe 6 in the axis of the stand, there being a reverse bend 35 intermediate its ends.

By this arrangement of the pipes it is evident that a loosening of the union 13 at the upper end of the drain pipe forms a swivel joint upon which the head may turn without disturbing the pipe, and by loosening the union 4 at the bottom of the supply pipe a swivel joint is formed upon which this pipe may turn when the head is rotated on the pedestal; and it is evident that such a rotation may be made for nearly a half turn in each direction from the position shown in the drawing before the bend of the supply pipe will impinge the head of the waste pipe, it being understood that a full half rotation is never required in practice.

In the modification shown in Fig. 3, the

supply channel 20 in the tubular arm 19' waste channel 21 is formed is not provided with a stop valve. The drain pipe 3 does not extend upward above the bottom of the head and the trap for the by flanges 36 and 37 at the side of the hollow head.

I claim:

1. A cuspidor stand or the like comprising a hollow pedestal, a hollow head rotatably mounted thereon, a bowl mounted on the head and an arm extending from the head to the side of the cuspidor having a water supply channel therein passing through the body of the head.

2. A cuspidor stand or the like comprising a hollow pedestal, a hollow head rotatably mounted thereon, a bowl mounted on the head and an arm extending from the head to the side of the cuspidor having a water supply channel therein passing through the body of the head and a stop valve in said channel.

3. A cuspidor stand or the like comprising a hollow pedestal, a hollow head rotatably mounted thereon, a bowl mounted on the head, and a tubular arm extending from the head to the side of the bowl having separate channels therein for carrying water through the head respectively to and from the hollow of the pedestal.

4. A cuspidor stand or the like comprising a. hollow pedestal, a hollow head mounted thereon, a bowl mounted on the head, an arm extending from the head to the side of the bowl forming a waste water channel extending downward into the head and a drain pipe extending upward into the head to a point above the end of the water channel, thereby forming a trap in the hollow head.

5. A cuspidor stand or the like comprising a hollow pedestal, a hollow head mounted thereon, a bowl mounted on the head, a tubular arm extending from the head to the side of the bowl having separate channels therein for carrying water to and from the hollow of the pedestal, a supply pipe communicating with the lower end and a faucet leading from the upper end of one channel, and an overflow pipe communicating with the upper end and a drain pipe leading from the lower end of the other channel.

6. A cuspidor stand or the like comprising a hollow pedestal, a head rotatably mounted thereon, two nipples depending from the head, one in the axis of the stand and the other at the side thereof, two fixed pipes in the bottom of the pedestal, one in the axis of the stand and the other at the side thereof, two riser pipes in the pedestal, and unions connecting the ends of the riser pipes with the nipples and the fixed pipes, the riser pipes being bent intermediate their ends and each having an axial connection at one end and a side connection at the other end.
